This book won the Hugo? For some reason, I expect books that win prizes like that to be something mindblowing. Guess what: this wasn't. Hannu Rajaniemi's book was, for example, even if I only understood half of it.

So this was something of a funny adventure / metastory, somewhat likable characters, easy to read, but I didn't find it to be anything special. Old man's war had ideas and it was a better book imho.
